反応手順
The process is carried out as in Examples 1 - 5 using 50.0 grams of a methanolic co-distillate (boiling range 66° - 78° C) containing 14.8 grams of 2-methoxy-4-methyltetrahydrofuran derived from methallyl alcohol as described in step (a), 30 ml of water and 5.0 grams of powdered copper chromite (Catalysts and Chemicals Co.). The mixture is heated at 180° C under 1000 psi of hydrogen for one hour. Analysis of the product mixture shows the presence of 9.3 grams of 2-methyl-1,4-butandiol (70% yield) and about 0.5 grams of 3-methyl-4-butyrolactone (4% yield).
